I'm sure this has been answered somewhere in the forums, but I cannot find it... I have a '73 K5 with a 350 that currently runs 31 inch BFGs with no lift. If I install ORD's 1" zero-rate lift, can I run 35's without rubbing? If so, are the stock axles and running gear up to the task? I do not beat on the truck very hard, but I do not want to have to be careful on the throttle ;-) A side note: My 'little' brother just bought a '69 K5 that has seen some pretty serious engine / driveline work. Somewhere north of 400 horses. We will probably be meeting next summer for a little brotherly competition, and I'm sure it will include a heavy chain between both vehicles... ;-0 My K5 has a fairly stock engine, the only mods are HEI and headers (no h-pipe). What advice do you guys have for gaining 50 - 100 horses? I have all winter to tinker and some $ to spend... Please throw down some advice so I can throw down the gauntlet next summer! Thanks!
